Software engineer who deals with large datasets, disk images, etc etc. Throughout the years I've had to have a big "scratch disk" with yet another bigger "archive" to support my work.

For my scratch disks I need at least 1TB locally (preferred 4+), and for my archive I need 16TB easy. I deal with everything from shape files, to GIS, to huge flat-file processing etc etc. I'm the guy who can take 10+ years of data and make business sense of it so storage is a constant headache/need.

To get ahead of someone telling me, "you're doing it wrong": no. No I am not. Just because you don't have the need doesn't mean there's not a market for it.
